First Top Charge

I just ordered the Freas, looking forward to being able to read through good glass. One of the many puzzles I have not been able to answer is when charging with the Mega Watt how do I need to wire in the volt/amp meter so it is reading what the battery charge is vs the Mega Watt output? I have the meter tied to the shunt on the negative output of the supply now. So how should I have it?
Thanks.

If you shut the Mega Watt off, but leave it attached to the batteries... it will continue to only give you a voltage reading, to the 1/10th of a volt, until you disconnect the Mega Watt cables from the battery terminals. Voltage readings will sag or drop based on amount of load applied currently to the battery, or if there is a surplus surface charge if no load is on the battery, the voltage could read higher. That voltage meter is only a barometer for the voltage of your battery and state of charge. The only thing absolute is what your specific gravity is, per battery. Forget what the voltage is for final determination for state of charge.
